Application filed January 8, 1916. Serial No. 70,919.

To all w hom t may concern:

Be itv known that I, SAMUEL V. REEVES, a citizen of the United States, residing at HaddOnield, in the county of Camden, State of New Jersey, have invented a new and useful Hot-flater Stove and Insulating-Jacket Therefor, of which the following is a specilication.

In hot water stoves as heretofore constructed, which are connected both to the boiler and to the radiators of the heating system, it has been necessary to call in a plumber to disconnect the radiators of the heating system in warm weather, and since the hot water stove is of suflicient capacity to heat the water both for the boiler and hot water heating system, it becomes dificult to run the stove without obtaining an excess of hot water.

In accordance with my present invention, I have eliminated the necessity of disconnecting any of the piping of the heating system, and I provide means for insulating the water jacket from the heat zone of the stove, and I also provide a water ring which is connected to the boiler, while the water jacket of the stove is connected to the hot water heating system.

I/Vith the above in view, my invention consists of novel means cooperating with the water jacket to insulate it from the fire.

It further consists of a novel construction and arrangement of an insulated jacket, which is inserted int-o the stove in summer time when it is not desired to utilize the heating system, and which is removed from the stove in the winter time when it is desired to utilize the heating system.

It further consists of a novel construction and arrangement of a water cylinder, a water jacket, and an insulating jacket.

It further consists of novel means for reducing the diameter of the fire pot.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description of my invention.

For the purpose of illustrating my invent-ion, I have shown in the accompanying drawings, typical embodiments thereof, which illustrate the principles of the invention and which will give reliable and satisfactory results in practice. It is, however, to be understood that these embodiments are typical only, and that the various instrumentalities of which my invention consists may be variously arranged and organized, but my invention is not limited to the precise arrangement and organization of these instrumentalities, as herein set forth,

Figure 1 represents a. sectional elevation of a hot water heating device and insulating means therefor embodying my invention.

Fig. 2 represents a section on line fcof Fig. l.

Fig. 7 represents a sectional elevation of another embodiment of my invention.

Fig. 8 represents a sectional elevation of a portion of my invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings My present invention is not limited to use in conjunction with the stove herein illustrated, but is preferably employed in conjunction with the type shown, which in its broad aspects corresponds to that described and broadly claimed in my prior patent for hot water stove, #1,156,929, granted to me on October` 19th, 1915.

1 designates the base of the stove, which carries in any desired manner, a grate 2 for supporting the bed of fuel. 3 designates a water ring comprising a casting having its bottom adapted to rest on the top of the base 1 and provided with a water chamber 4, with which communicates a cold water pipe 5 leading from the source of liquid supply, and also communicating with the water chamber 4t is a pipe 6, which is connected to the boiler. The inner face of the water ring 3 is preferably cylindrical, as indicated at 7, and the outer face isrpreferably provided with radiating ribs S which preferably register with and form a continuation of the radiating ribs 9 of the stove cylinder 10 rI`he water ring 3 is provided on its top face with au annular iiange 11 located near its inner periphery and over this flange the outwai'dly extending flange 12 of the stove cylinder 10 is adapted to fit, it being noted that the opposite end of the stove cylinder is provided with an outwardly extending flange 13 having the same conformation as the flange 12, whereby the stove cylinder may be readily reversed, when desired.

14 designates a ring interposed between the bottom wall 15 of the stove cylinder and the top face 1G of the water ring. The stove cylinder 10 is provided with a water chamber 17, so that such cylinder forms a water jacket. The core chamber of the water jacket has its greatest diameter atits medial point equidistant from the top and bottom. The upper outer annular wall ofthe `jacket converges upwardly from said medial point, and the lower outer annular wall of the jacket converges downwardly from the 1nedial point with the inclination of said upper and lower walls substantially the same with respect to the longitudinal axis of the water jacket. The inner wall 18 of the water acket normally forms the fire pot of the stove. i

19 designates a cold` water pipe leading from the cold water supply or forming the return pipe andl communicating with the lower end of the'water chamber 17. 20 designates a hot water pipe communicating with the upper end of the water chamber 17 and connected with the hot water heating system. 21 designates the top of the stove which seats on the top face 22, which corresponds in construction with the bottom face 15, and this top 21 is provided with the removable lids 23 and with acollar 24 adapted to receive the usual smoke pipe through which the products of combustion pass to the chimney.

25 designates an insulating jacket, consisting ofv a bottom ring 2G having spacing 'lugs 27 extending therefrom. 28 designates the upper ring, and between the rings 26 and 28 is interposed a cylinder 29, preferably of cast iron, and spaced from this cylinder 29 by means of the lugs 27 is an outer cylinder 30 which is preferably made of sheet iron or any suitable insulating material, thereby forming an air space 31. 32 designates stay rods connected with the upper and lower rings 26 and 28, respectively, in order to maintain the parts of the jacket 25 in assembled position. The upper ring 28 is provided with apertures 33, through which the heat generated in the chamber 31 may pass.l lVhen the insulated jacket 25 is placed within the water jacket of the stove, the outer portion of the lower ring 26 rests upon the upwardly extending flange 11y of the water ring, and an air space 34 (see Fig. 1) is formed between the jackets. The upper ring 28 is provided with apertures 35, through which the heat generated in the air chamber 34 may pass. It will be seen thatv in the form shown in Fig. 3, the inner cylinder 29 ofthe insulatedjacket 25 has a cylindrical contour, and this form gives satisfactory results, wherein the fire pot is of con'iparatively small diameter, but in stoves wherein the fire pot is of large diameter, 1 preferably employ an-inner cylinder', as seen in Fig. 5, it being understood that it is within the scope of my invention to have the inner cylinder cylindrical or converging toward the center in any desired manner. Since the construction of the water ring and water jacket are substantially the same as in Fig. 1, I have given to corresponding parts the same reference characters.

In this embodiment, 3G designates the bottorn ring of the insulating jacket which rests upon the flange 11 of the water ring 3. 37 and 38 designate cylinders spaced from each other to form an air chamber 39 which communicates with apertures 40 in the upper ring. 41. Between the cylinder 38 and the wall 18 of the water jacket, an air passage 42 is formed, which communicates with apertures 43 in the upper ring 41. The4 inner cylinder of' the insulating jacketl islformed in sections and' consists of a lower section 44 and an upper section 45 of the sameconformation, these being preferably made from the same pattern, and each being provided with foot flanges 46 which rest on their respective rings, and their inner ends are providedwith end faces 47, whereby they will be in Vclose contact, when assembled. The walls of a section, as 45, for example, converge toward one end, so that when the cylinder sections are assembled, a passage 48 is formed which converges from the ends toward its medial line. The cylinder formed by the sections 44 and 45 forms with the cylinder 37 an air chamber 49, which communicates b y means of ports 50 in the upper flange 46 with the chamber in the top 21. 51 designates stay rods connectedv with the upper and lower rings to secure the parts in assembled condition.

It is within the scopeV of myA invention to have the insulating jacket terminate any desired distance from the top of the stove, and in Fig. 7,1 have shown the insulating jacket as being made in sections, thev upper one of which. may be dispensed with, ifV desired. 52 designates the bottom section of the jacket which corresponds in construction to that seen in Fig. 3, except that it isof less length. In' some cases, it isy desirable to place above the jacket 52, a cylinder 53, which is provided at its upper end with an outwardly extending annular liange 54, pro vided with apertures 55, and this cylinder 53 forms with thewall 18 of the water jacket, an air chamber 5G.

In stoves of this character as ordinarily constructed, it is necessary, if a single stove is employed, to disconnect it in the summer time from the hot water lheating system, and connect it to the boiler, which is used for household purposes. In the winter time, it becomes necessary to disconnect the stove from the boiler and connect it to the hot water heating system. In accordance with my present invention, it is unnecessary to go to this expense, since I provide a water jacket which is connected with the hot water heating system, and I provide a water ring which is connected to the boiler. If the stove is of suiiicient capacity to operate both of these systems, its capacity is too large when one of these systems is not employed, and I therefore provide a novel construction and arrangement of insulating jacket which may be readily inserted or removed through the top of the stove by simply removing` the stove lids or stove tcp. The insulated jacket rests upon the top of the water ring and insulates the water chamber 17 from the heat of the fire, and at the same time, it reduces the diameter of the fire chamber, so that a smaller fire can be employed.

It will be understood that in many cases arising in practice, the water ring is not employed, and a solid casting is used in place thereof.

The portable insulated jacket is intended to be used in fire chambers, fire pots, or iire boxes of water stoves or boilers, and may be any shape that nearly conforms to the iire chamber, fire pot, or fire box in which they are to be used. Itis designed primarily to insulate the water chamber of such stoves and boilers when it contains water for heating system, such as radiators in various forms, and it is more applicable to this particular use when two or more water circulating chambers are heated by the same iire. The upper or larger water chamber may be insulated from fire contact and the heat of the iire, irrespective of what it is connected to, whether to different forms of radiators or to a reservoir or vessel containing water. The insulating jacket may also be employed when for any purpose it is desired to have a fire in the stove before the radiators or reservoirs are connected to the water chamber, and when such chambers are empty. It is only when the water chamber is filled that a iire can be carried without cracking the fire wall of the water chamber, unless an insulated jacket is inserted. By the employment of a plurality of circulating` chambers, one is enabled to supply the kitchen and bath boiler with a separate supply, which does not pass through the radiators at all times, and this is particularly desirable when employing stoves and water boilers for the double purpose of heating as well as supplying kitchen and bath water. It enables one to use the same stove at all times, either separately or in combination, to

provide one or a plurality of circulating water chambers, means being employed to insulate the chamber which is not to be used.

It is to be understood that in many cases arising in practice, a ring, suoli as 52, seen in Fig. 8, is employed which serves to raise the water ring above the base of the stove, so as to form a pocket for the ash formed by the bed of fuel, so that such ash will not insulate the water chamber of the water ring from the heat of the fire. This lower ring 52 varies in dimensions in accordance with the size of the stove with which it is employed, and in practice, it is ordinarily used only with stoves of large size.

It will be seen that in the embodiment seen in Fig. 5, the cylinder which forms the fire-pot is separate from the other portion of the insulating jacket and rests on the lower ring thereof, so that it may be readily inserted into the other portion of the insulated jacket after it has been inserted within the water jacket of the stove, and in practice, it is preferably made this way, since it is made in sections and disconnected from the other cylinders in order that it may be the more readily handled.

It will now be apparent that I have devised a novel and useful hot water stove and insulating jacket therefor, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described typical embodiments thereof which will give in practice satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. A

I-Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent, is
